Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Fingolimod Impurity 16 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 335.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Fingolimod Impurity 16 (CAS 1404433-87-9) is a certified pharmaceutical impurity reference standard with the molecular formula C21H37NO2 and a molecular weight of 335.52 g/mol.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Fingolimod Impurity 16 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
